Should this work?

[Manu]

This works fine:
  string x = find("Hello", 'H');

This doesn't:
  string y = find(retro("Hello"), 'H');
  > Error: cannot implicitly convert expression (find(retro("Hello"), 'H'))
of type Result!() to string

Is that wrong? That seems to be how the docs suggest it should be used.

On a side note, am I the only one that finds std.algorithm/std.range/etc
for string processing really obtuse?
I can rarely understand the error messages, so say it's better than STL is
optimistic.
Using std.algorithm and std.range to do string manipulation feels really
lame to me.
I hate looking through the docs of 3-4 modules to understand the complete
set of useful string operations (std.string, std.uni, std.algorithm,
std.range... at least).
I also find the names of the generic algorithms are often unrelated to the
name of the string operation.
My feeling is, everyone is always on about how cool D is at string, but
other than 'char[]', and the builtin slice operator, I feel really
unproductive whenever I do any heavy string manipulation in D.
I also hate that I need to import at least 4-5 modules to do anything
useful with strings... I feel my program bloating and cringe with every
gigantic import that sources exactly one symbol.
